REINFORCING CEMENT RENDERS OVER JOINTS
REINFORCING CEMENT RENDERS OVER JOINTS
(OP)
Its standard practice to create joints in the cement render at the junctions of brickwork and reinf conc. But I have a project where the Architects are insisting, for aesthetic reasons, on not having a joint. I'm investigating reinforcing the render over the joint in order to accomodate the movement in a series of micro-cracks. The concept would be to de-bond the render from the substrate for about 5" on both sides of the joint and then to reinforce the render for another 6" beyond that. Thereby creating a total of 22" of reinforced render. (the redner is typical 3/4" thick)
Comments anyone?

Thanks for your replies. I'm in South Africa and I'm not aware of any commercially available "plastic"
stucco. We typically add hydrated lime to improve workability and to improve plasticity.
I was thinking of the waterproofing industry which routinely will torch on waterproofing over a joint by laying an unbonded section of membrane over the joint and then torching on over that. Obviously there are order of magnitude differences in flexibility between cement stucco and bitumen impregnated felt, but I'm still thinking that the concept is "worth a shout"
In Italy some years back, I noticed that they plastered over all their concrete/brick junctions using only a thin fibreglass mesh! I would love to get back there now and see how it all performed.
Thanks again
Alten
